digitalmars.D.learn - const strings (D1.0)
- Bill Baxter (12/12) Mar 03 2008 Is this correct behavior?
- Derek Parnell (10/25) Mar 03 2008 The problem is that these are NOT strings, but fixed length character
- Bill Baxter (3/29) Mar 03 2008 Ooohhh. Great. That works. Thanks a lot.
Is this correct behavior? import std.stdio; import std.string; const MM_REAL_STR = "real"; const MM_INT_STR = "integer"; void main() { writefln(toString(MM_REAL_STR.ptr)); // --> prints "realinteger" } I thought all literal strings were supposed to be zero terminated. That doesn't go for const strings? --bb

That doesn't go for const strings?The problem is that these are NOT strings, but fixed length character literals, and those beasties don't have trailing zeros. Try this instead ... const string MM_REAL_STR = "real"; const string MM_INT_STR = "integer"; -- Derek Parnell Melbourne, Australia skype: derek.j.parnell
